A proposed AD would require the installation of de-icing boots on the landing-gear struts and cargo pods, as well as  other changes to deicing equipment and procedures, on nearly 750 U.S.-registered Cessna 208 Caravans. The directive stems from the FAA’s investigation into nine icing-related incidents within the past few months and six accidents in the previous two icing seasons. (Wing strut boots were part of the aircraft’s original de-icing package.) Comments on the proposal are due August 22. For more information, contact the FAA in Atlanta at (770) 703-6064. This is the second AD to result from the FAA’s investigation into Caravan icing accidents and incidents: a March directive called for more stringent visual and tactile preflight inspections.
